Report: Macrozoobenthos: Leybucht; Development (1984)»
Description
These studies are part of the Leybucht project.
The research centre has also dealt with hydrological conditions (LIEBIG 1984, NIEMEYER 1984), morphology (STEPHAN 1984) and sedimentology (RAGUTZKI 1984). The aim of these works is to assess the construction project in terms of its impact on the entire area of Leybucht and on its future development.
Concluding remark:
Finally, it can be said about the future prospects of Leybucht: The insights gained from morphological analysis (height growth) and vegetation development suggest that the landing progresses only slowly. The planned construction project is expected to have little impact on the course of natural development, as the Leyhörn peninsula leaves the current current and sea-going conditions unaffected. According to human time, the book is thus granted a longer existence. However, time gradually works in favour of salt marshes and at the expense of wattages. This development can have consequences for the bird life, as it changes the currently particularly favourable conditions between breeding, food and resting biotopes. The cotton wool fauna of the Leybucht is not unusually rich in biomass, as assumed several times. However, it is made up of easily available species for Vögle and possibly of particularly productive species. In the long term, there are signs of scarcity, as height growth and area reduction of cotton wool will reduce biomass. The continuation of the areas claimed by the Leyhörn peninsula reinforces this development. In order not to change the area ratio between wadding and salt marshes unnecessarily and not prematurely, it is recommended that the land reclamation works be discontinued.
The Bay “Leybucht”, located in the lower reaches of the Ems Estuary, was originally bound for total closure by land reclamation. However, in the course of the last 15 years the view changed because the extraordinary ecological value of the bay was recognised. Its extensive Saltmarshes and mud flats form a unique habitat for breeding and migrating waders and waterfowl. So, a total embankment seemed no more acceptable. Instead, a plan was developed to embank about 10 km² of foreland and tidal flats mostly outside of the Leybucht proper, in order to create a water reservoir for Hinterland drainage and a new and deep channel for the fishing village Greetsiel. In the present study special aspects of the ecological impact of this coastal engineering project are investigated.
